Review & Installation Video

I’m Justin from AmericanMuscle.com, and this is our handling bolt-on build-up for all ’99-‘04 Mustang GTs. The goal with this build is pretty simple, we’re looking to take some basic suspension components, install them on our 2000 GT here, in an effort to make it handle a lot better than it does now in stock form. Now, individually, installed each of these parts will make a slight difference in your car’s handling. However, when installed together, like we’re going to do today, they should make a substantial difference in our cars’ handling and should make our GT handle like it’s on rails. First up on the list to install is this black strut tower brace that we have laid into place, just so we can see how it’s going to sit. Now this is a very popular first step for making your car handle a little bit better, and it’s going to be pretty easy on your wallet as well. Now basically, this is going to firm up the front end and reduce chassis flex and body roll. I have to admit, that black powder coated finish is going to look pretty cool under the hood as well. The next mod we’re going to go with for our handling pack is a set of these QA1 Caster Camber Plates. These are going to be very valuable for getting our GT’s alignment back in spec after we lower the car. A properly set up alignment will not only help your cars handling, but it’s also going to save your tires from premature wear. Speaking of lowering the car, what suspension build would be complete without a set of lowering springs. We’re going to install a set of these SR Performance lowering springs which will lower our GT roughly an inch and a half or so on all four corners. Not only will this help our ride handle a lot better thanks to that lower center of gravity, but it’s also going to help our appearance as well by getting rid of that ugly wheel gap. Last and certainly not least are these front and rear sway bars from Eibach, sway bars are one of the biggest factors to reduce body roll and are a great tool for fine tuning your suspension. From the factory most Mustangs have the tendency to plow or push through turns, this is referred to as under steer. By installing a larger rear sway bar and tweaking the front, you’re actually going to eliminate that under steer and introduce a little bit of over steer, which means the rear of the car is going to come through the turns much quicker, and actually make the car a little bit more fun to drive. So those are the parts we have in store for our GT here today, now let’s get everything installed so I can get our GT out of the ‘shop and onto the streets, and see the difference this handling pack makes. Alright so I just got our 2000 GT out of the ‘shop and onto the street here, and it took me all of 5 seconds the realize what a difference this handling pack makes to our ride. Gone is the kind of floaty, disconnected feeling that our Mustang used to have, and it actually now feels like a sports car, it feels like it should - much more firm, much more planted, even going straight, obviously through the turns it’s a lot better as well. The car just feels like it wants to respond to your actions a lot more, making it feel like you’re actually part of the car, which is great, and you can just slide turn to turn, going straight here like I said, the car just reacts well to whatever you want to do to it. We have a nice right hander coming up, let’s see how the car reacts with our new mods installed. All right, so much better, the car is just so firm and so planted going through those turns, that can definitely be attributed to those sway bars working with that SR Performance strut tower brace to really reduce our body roll and our chassis flex. I got a nice left hander coming up as well. Oh yeah, you can totally come into a turn now with much more speed and much more confidence going through the turns. The nice thing about the springs too, obviously they lower the car making it look a lot better and handle a lot better, but it’s also better for acceleration and our braking. The car doesn’t want to nose down now when you’re hard on the brakes coming into a turn, making it feel a lot more solid. Those QA1 Caster Camber plates are probably not going to make the biggest difference in your everyday drive however it was able to get our car back into spec after we lowered it about an inch and a half, just so we didn’t chew up our tires and made for a lot better handling. So there you have it, this handling pack really made a world of difference on our GT and really made our car a lot more fun to drive. Be sure to check out some of our other ’99-’04 bolt-on build ups where we work on our appearance, help get our GT off the line, and give it some more power.

Superior Quality and Materials. Eibach manufactures their Anti-Roll Sway Bars from cold-formed, high-strength aircraft-grade steel for precision performance, and are completed in a red powder coat finish for great looks and long life.

Application. This Eibach Anti-Roll Sway Bar Kit is designed for use on the 1994 to 2004 coupe and convertible Mustangs, including the V6, GT, Bullitt, Mach 1 and 1994-1998 SVT Cobra models. Does not fit 1999-2004 IRS equipped SVT Cobra.

Will adding sway bars like these decrease ride comfort and increase road noise? My Mustang is my daily driver, and I'm thinking about adding something like this after replacing control arms, springs, shocks, struts, etc, but I'm worried if I go too far with suspension mods like these, my car won't drive as comfortably in the long run. I want to find a balance.

An upgrade like the Eibach Anti-Roll Sway Bar Kit will actually improve your ride. It will help prevent body roll around the corners and bends. The ride comfort really comes from your shocks, struts, and springs. You will only notice a benefit with this sway bar kit in ride handling and comfort.

I forget what it is, but it comes with the instructions and paperwork. Eibach is an extremely reputable, and AM has a great write-up on installation.

I do not believe so but I'd say any mechanic would be able to help. In my case, the mechanic took one bar off and replaced the bar; there was no discussion of torqueing...nor was it mentioned in the instructions as I recall.
I used these bars, plus the upper front and rear upper strut bars on my 2000 GT convertible and the suspension up-grade was complete and amazing. No more cowl twist. I suggest if you do the lower, do the upper bars, too...It will finish the job!!

Yes, these will help make the car more "neutral" by reducing body roll in the corners, but if you're even a little serious about racing I'd suggest doing more than just sway bars. Most suspension parts are relatively cheap and easy to install. I'd consider going down the list of usual suspects starting with rear upper and lower control arms and MM subframe connectors. They'll both help flatten you out in the corners fairly dramatically for about 500 all together. Hope this helps.

I installed an Eiback front anti-roll kit #3518.310 and a rear kit #3510.312 . We stayed with the standard Mustang front end alignment specs. We did install Eibach Pro-Kit #3518.140 front and rear springs which lowers the vehicle 1.5 to 2 inches.
This Mustang can take a corner now with the best of them. It does ride a little rougher now.

All I can say is that the Eibach sway bars are quite a bit beefier than stock and do improve stability (especially the front bar. I'm glad I bought the set.
I cannot say whether or not they'd clear your exhaust system because the bars installed exactly in the same manner as the stocks. This seems to be an apples and oranges issue in that I believe you have a problem aside from the bars.
My suggestion would be for you to re-route or re-clamp your catback in such a manner that eliminates contact. Concentrate on improving the exhaust install. Hope this helps or gives you something to think about to solve your problem.

I had the same problem with my magnaflow exhaust. The sway bars are in the same location but the new one is bigger. I had to go take mine to the muffler shop and they cut out the elbow and relocated further back to give me clearance. It cost like 80 bucks to do both sides and not hearing the banging anymore is so worth the money.

I can honestly feel the difference when i corner when i added these to my gt. BUT i also added supporting mods before this. I have a strut tower and body braces welded on with all this the car handles perfectly.

Extremely well done parts, exact fit, firmed up my suspension. Only problem: the links provided are TOO SHORT!!!! Tried all the possible ways to fit them..... never worked, had to reinstall the OE ones.

My 97 cobra was feeling a little loose and just not solid over all on the road so I got new koni struts and shocks and steeda bump steer kit and it helped but still felt a little loose...got the Eibach front and rear sway bar kit and it tightened everything up! If your stang is feeling loose and sloppy you can't go wrong with this kit

I've got an 2004 GT, with OE springs and Koni's all around. With the car on jack stands, you do the job no problem. Kits goes on easy and you will need to re-use your front links if your car is has the factory springs. I'm impressed with the way the car handles now, the sway bars really eliminate suspension slop and keeps the car planted.

This was a very straight forward product to install. After installation I noticed that the car was much more stable. Since I installed it on my 2003 V6, the rear bar was an addition as there was not installed at the factory. It corners much flatter and makes the care feel more stable. I am very pleased with the result. I added Koni shocks at the same time and they too help the stability.

These bars perform exactly as advertised. I was really surprised how much better they made the car feel. The install was not bad at all, although I did have a friend help me out. Getting both sides lined up and bolted on would be frustrating without another person helping. We took our time with it and it took about 3 hours, so not too bad especially for the results you get. Like the others, I too found that the supplied end links were too short, so i just put the new bushings on the oem ones and it was fine. Actually pretty much all the hardware in the kit kind of sucked honestly, I suggest either re-using the stock bolts or getting new ones for the rear. Overall my Mach 1 feels so much more planted and confident through the corners. With my coilovers and this kit, there is no more wasted motion and it just feels like a sports car should. It transfers weight nicely and is so much more responsive for quick movements. They also look awesome under the car in that red. One of the best mods I've done, wish I had done it sooner!

Coming from a v6 without a rear sway bar this took so much roll out of my car. The install was simple and straight forward. It took maybe 2 hours not trying to rush it. With my sway bars, my strut tower brace, and my new rear control arms, my stang loves to take corners. I highly recommend this product to anyone.

So I've been thinking about how I can further improve the handling of my 98 Gt. I purchased these sway bars because i figured it would help. Boy was I surprised at just how much the handling improved!! I am completely satisfied with my purchase and would highly recommend these sway bars to anyone. I cannot speak for the quality of the other sway bars that AM offers but I can say that going with the Eibach sway bars is a great way to go.

This really needs to be the starting point for your suspension upgrade !

The kit came in a timely manner (thanks, AM!), and everything fit as designed; I didn't experience any of the fit/hardware problems that other reviewers mentioned, so everything installed swiftly and easily without help. I used cargo straps to support the rear bar during installation and zip-ties held the front during installation. This allowed the bars to be positioned and adjusted as needed. A previous review mentioned supporting the front bar from underneath to help thread the top bolts on supplied end links; worked like a charm! The performance of the kit is extraordinary! It flattens out the corners and allows the kind of driving the car was designed for!

As most of you know the 99-04 New Edge's did not come from the factory with a rear swat bar. I caught these on sale and have been very pleased with them ever since. The only problems I had were from the nuts and bolts supplied for the rear sway bar. Had one nut come completely off the vehicle and the other was about to on the drivers side. Went to the hardware store and got 3/8-16 bolts, lock washers, and nuts. Not worries about it since. But great improvement to those wanting to tighten up the handling!

AM had the best price with no shipping costs, what a great deal. Other vendors had the same price but wanted 20 dollars or more to ship. Also, the how to instructions and videos for installation are very helpful. I couldn't be more pleased with my purchase.

I have always been into cars, specifically Mustangs. But it wasn’t until I owned my first mustang that I really got in to them. I was I need of a car at the time and knew someone who owned a dealership and he had a 2000 Mustang convertible there. Being my first Mustang I didn’t know much about them...
